Information provided by India's National Investigation Agency (NIA) on militant activities in both countries 'cannot be ignored', says a home ministry official, reports bdnews24.com.
"India suspects there are militants in both Bangladesh and India and that they have to be traced.
"We think their call cannot be dismissed," Senior Secretary Md Mozammel Haque Khan told reporters Monday.
A team of NIA, now in Bangladesh, sat with the top security officials Monday.
The introductory meeting at the home ministry was attended by chiefs of different intelligence agencies as well as high officials of police, RAB and BGB.
A four-member NIA team led by its Director General Sharad Kumar arrived in Dhaka Monday morning.
The agency has been investigating Jihadi networks after the Oct 2 blast at a house in West Bengal's Burdwan town.
That, Indian investigators say, had been turned into a factory for making Improvised Explosive Devices (IED) by militants from banned outfit Jamaat-ul-Mujahideen Bangladesh (JMB).
Two suspected militants died in the explosion that rocked the Burdwan house and their two wives, believed also to be trained by the JMB, were caught.
The incident led to the unravelling of a wide terror network, the investigators said, also claiming the militants were out to eliminate two top Bangladesh politicians - Prime Minister Sheikh Hasina and BNP Chairperson Khaleda Zia.
The NIA felt the need to investigate in Bangladesh and the visit was set up after talks with Dhaka.
"Both the countries agree that they would not let miscreants use their land for militant activities. We had a very brief meeting.
"A six-member committee has been formed to interact with the four-strong NIA team. They would discuss the matters in details," Khan told reporters after Monday's meeting.
Additional Home Secretary Kamal Uddin Ahmed will lead the six-member body, added the senior secretary.
The NIA team held a separate meeting with RAB and intelligence officials after the introductory meeting Monday.
